Abstract

See full text

A transient liquid phase (TLP) composition includes a plurality of first high melting temperature (HMT) particles, a plurality of second HMT particles, and a plurality of low melting temperature (LMT) particles. Each of the plurality of first HMT particles have a core-shell structure with a core formed from a first high HMT material and a shell formed from a second HMT material that is different than the first HMT material. The plurality of second HMT particles are formed from a third HMT material that is different than the second HMT material and the plurality of LMT particles are formed from a LMT material. The LMT particles have a melting temperature less than a TLP sintering temperature of the TLP composition and the first, second, and third HMT materials have a melting point greater than the TLP sintering temperature.
